# Configuration parsers

All parsers inherit from {class}`~baggianalysis.core.BaseParser` and override the `_parse_stream` and, possibly, the `_parse_file` methods. After a parser has been initialised it can be used to build a single system through its {func}`~baggianalysis.core.BaseParser.make_system` method or a whole trajectory by using it to initialise a [Trajectory](trajectories.md) object.
